Variant summary

Our verdict is Pathogenic. The variant received 11 ACMG points: 11P and 0B. PM1 PM2 PM5 PP2 PP3_Strong

The NM_005614.4(RHEB):​c.104A>T​(p.Tyr35Phe) variant causes a missense change. The variant was absent in control chromosomes in GnomAD project. In-silico tool predicts a pathogenic outcome for this variant. No clinical diagnostic laboratories have submitted clinical-significance assessments for this variant to ClinVar. Another variant affecting the same amino acid position, but resulting in a different missense (i.e. Y35L) has been classified as Pathogenic.

Genes affected

RHEB (HGNC:10011): (Ras homolog, mTORC1 binding) This gene is a member of the small GTPase superfamily and encodes a lipid-anchored, cell membrane protein with five repeats of the RAS-related GTP-binding region. This protein is vital in regulation of growth and cell cycle progression due to its role in the insulin/TOR/S6K signaling pathway. The protein has GTPase activity and shuttles between a GDP-bound form and a GTP-bound form, and farnesylation of the protein is required for this activity. Three pseudogenes have been mapped, two on chromosome 10 and one on chromosome 22. [provided by RefSeq, Jul 2008]

ACMG classification

Our verdict: Pathogenic. The variant received 11 ACMG points.

• PM1: In a chain GTP-binding protein Rheb (size 180) in uniprot entity RHEB_HUMAN there are 7 pathogenic changes around while only 0 benign (100%) in NM_005614.4
• PM2: Very rare variant in population databases, with high coverage
• PM5: Other missense variant is known to change same aminoacid residue: Variant chr7-151490962-GT-TA is described in ClinVar as Pathogenic. ClinVar VariationId is 3238630.Status of the report is criteria_provided_single_submitter, 1 stars.
• PP2: Missense variant in the gene, where a lot of missense mutations are associated with disease in ClinVar. The gene has 5 curated pathogenic missense variants (we use a threshold of 10). The gene has 0 curated benign missense variants. Gene score misZ: 2.2985 (below the threshold of 3.09). Trascript score misZ: 0.028093 (below the threshold of 3.09). GenCC associations: The gene is linked to complex neurodevelopmental disorder.
• PP3: MetaRNN computational evidence supports a deleterious effect, 0.958
